Answer:
52
Step-by-step explanation:
A cubical box without a top is 4 cm on each edge containing 64 identical 1 cm cubes.
We have to find the number of small cubes that actually touch the box.
Now, there are 4 layers of 16 cubes from bottom to top.
In the bottom-most layer, all the 16 small cubes will touch the bottom of the large cube.
Again, from the top three layers, only the outer small cubes will touch the sides of the large cube.
So, there are 12 small cubes in each top three layers that will touch the large cube.
Hence, in total there will be (16 + 12 ×3) = 52 small cubes that actually touch the large cube box. (Answer)

Step-by-step explanation:
Population of Egypt in 2005 is 72.64 million.
<u>Step-by-step explanation:</u>
We have ,The estimated population of Egypt in 2011 is about 81 million. this is a 1.8% growth rate over the previous year. According to question , population in year 2010 = population in year 2011 - 1.8% of population in year 2011 i.e.
population in year 2010 = = 79.52 million
Similarly, population in year 2009 = = 78.10 million
population in year 2008 = = 76.70 million
population in year 2007 = = 75.32 million
population in year 2006 = = 73.97 million
population in year 2005 = = 72.64 million
Therefore, population of Egypt in 2005 is 72.64 million.
Answer:
it equals -1.5
Step-by-step explanation:
you take 7.0 and put the 5.5 under it you subtract and just change the sign to a negative since 7.0 is bigger does that make sense?
17.1
17 times 11 is 187 leaving 1, so that will be your remainder
